Good interview with Steven Solie - this bit stood out to me: "Although Hyperion has been using serial numbers for copies of AmigaOS since 4.0, it won't reveal sales numbers. Solie's 'personal guess' is that the system has 2000-5000 users. 'If you include all the various Amiga clones and emulators we would probably be talking about around 10000 users [in] total,' he adds, 'it is really difficult to judge because a majority of the users are rather quiet.'" Fascinating number - lower than I anticipated.
